Abstract

A novel heterogeneous catalyst, [Zn_2.15Al_0.86(OH)_6.02] [Mn]_0.19[C₆H₅COO]_0.48·2H₂O, where {[Mn] = chiral sulfonato⁻salen-manganese(III) complex, Na₂MnC₂₀H₂₂N₂S₂O₁₂Cl, intercalated into Zn^II–Al^III layered double hydroxide host}, has been synthesized and found to be an effective heterogeneous catalyst for the stereoselective epoxidation of R-(+)-limonene using molecular oxygen. The catalyst could be recycled without loss of performance.
